NCP167
LDO Regulator
- Ultra-Low
Noise, High PSRR, RF and
Analog Circuits
700 mA
The NCP167 is a linear regulator capable of supplying 700 mA
output current. Designed to meet the requirements of RF and analog
circuits, the NCP167 device provides low noise, high PSRR, low
quiescent current, and very good load/line transients. The device is
designed to work with a 1
mF
input and a 1
mF
output ceramic capacitor.
It is available in two thickness ultra−small 0.35P, 0.65 mm x 0.65 mm
Chip Scale Package (CSP) and XDFN4 0.65P, 1 mm x 1 mm.
